摘要：

A series of phosphoryl podands of acid type, differing in the length of the polyether chain and structure of the terminal group, were synthesized. The compounds obtained were tested as complexing components of impregnation-type sorbents. The regular trends of the Mo sorption from model solutions of ammonium molybdate in HNO3 in relation to the qualitative and quantitative composition of the sorbents were studied by extraction chromatography. The composition of a new impregnation-type complexing sorbent for selective recovery of Mo from nitric acid solutions was developed and optimized, and conditions were determined for its practical use. The sorbent allows efficient recovery of 99Mo and its separation from products of reprocessing of irradiated uranium materials in process solutions of the Mayak Production Association. The sorbent also allows separation of 99Mo and 99m Tc, which makes it potentially suitable for use in 99Mo/99m Tc generators of chromatographic type. © 2015 Pleiades Publishing, Inc.
